Authentication, authorization and encryption in large scale distributed Grids are usually based on a Public Key Infrastructure (PKI) with asymmetric encryption and X.509 – Proxy certificates for user single sign-on to resources. This approach, however, introduces processing overhead, that may be undesirable in near real time Grid applications (e.g. Grids used for time critical instrument monitoring and control). To alleviate this we introduce in this paper a Symmetric Key – Kerberos based approach that scales in large Grid environments. We present a Use Case Scenario to test and validate the proposed Architecture, in case of numerous time-critical requests running in parallel.
